Arctic Ocean Shows New Record Low Sea Ice

Image
by Albert Kallio Both the sea ice thickness and sea ice area have fallen to new record lows for this time of the year (22.11.2015), even surpassing all of the worst previous years. From Naval Research Laboratory image - view  animation Immense thrust of fast moving sea ice is pushing through at the full width of the Fram Strait between Norway and Greenland. This amounts to huge transport of latent coldness out of the Arctic Ocean to North Atlantic, while the constantly forming new sea ice (as temperatures are below 0°C) is generating heat to keep the surface air temperatures higher across the Arctic Ocean. Thus, heat is constantly being added to the Arctic Ocean while heat is taken away from the North Atlantic Ocean. The normal sea ice area for this time of year is 9,625,000 km 2 , whereas the sea ice covers currently just 8,415,890 km 2, , which makes that 1,209,120 km 2  sea ice is missing from the normal (22.11) sea ice area. The combination image below shows the jet stream (Novembe

Rapid Transition to a Clean World

100% clean and renewable wind, water, and solar (WWS) all-sector energy roadmaps for 139 countries of the world [ click here for explanatory video of above image ] Above image is from  an excellent study by Jacobson et al., showing that it is technically feasible and economically attractive to shift to clean energy facilities between now and 2050. This will create net jobs worldwide. It will avoid millions of air-pollution mortalities and avoid trillions of dollars in pollution and global warming damage. It will stabilize energy prices and reduce energy poverty. It will make countries energy independent and reduce international conflict over energy. It will reduce risks of large-scale system disruptions by significantly decentralizing power production. Mark Jacobson: A 100 percent Renewable Economy Given that there are so many benefits and there are no technical and economic barriers to complete a 100% shift by the year 2050 (and 80% by 2030), why not make an even faster transition?

Ocean Heat

Sea Surface Temperatures Sea surface temperatures were as high as 15.8°C or 60.4°F near Svalbard on November 7, 2015, a 13.7°C or 24.7°F anomaly. Let this sink in for a moment. The water used to be close to freezing point near Svalbard around this time of year, and the water now is warmer by as much as 13.7°C or 24.7°F. [ click on image to enlarge ] Above image further shows that sea surface temperature anomalies as high as 6.7°C or 12.1°F were recorded on November 7, 2015, off the coast of North America, while anomalies as high as 6°C or 10.9°F were recorded in the Bering Strait. NOAA analysis  shows that the global sea surface in September 2015 was the warmest on record, at 0.81°C (1.46°F) above the 20th century average of 16.2°C (61.1°F). On the Northern Hemisphere, the anomaly was 1.07°C (1.93°F). [ click on image to enlarge ] How did temperatures get so high near Svalbard? The answer is that ocean currents are moving warm water from the Atlantic Ocean into the Arctic Ocean. The oc
